Thermostat Savings Calculator
Estimate how much you can save on heating and cooling bills by adjusting your thermostat a few degrees.
Estimated Savings
Thermostat setback savings follow the widely cited guideline from the U.S. Department of Energy:
You can save about 1% on your heating/cooling bill for each degree you set back the thermostat for 8 hours.
Savings % = Degrees Adjusted x Hours Setback / 8 x 1%
Dollar Savings = Annual HVAC Cost x Savings %
Tips for maximizing savings:
- Winter: Set to 68degF (20degC) while home, 60-62degF (15-17degC) while sleeping or away
- Summer: Set to 78degF (26degC) while home, 85degF (29degC) while away
- A programmable thermostat can save $150-180/year automatically
- Smart thermostats can learn your schedule and save an additional 10-15%
Average annual HVAC costs (US): $1,000-$2,500 depending on climate and home size.
